No. 786,753 Claims priority, application Germany Jan. 21, 1958 12 Claims. (Cl. 234-115) The invention relates to signal recording devices and particularly to an electromagnetically controlled punching arrangement for code signals.

It is inadvisable to derive the power for punching telegraph tape directly from the armature of a receiving magnet, since in this way, it is impossible to obtain a clean and wear-resisting tape. For this reason the punching movement may be controlled by a member, preferably in the form of a frame, which is reciprocated by means of an auxiliary force. The receiving magnets may control rail or lever-like intermediate members each of which is located, when the armature of the respective receiving magnet is in one end position between the control member and the associated punch and thus couple these two parts together, and which, when the armature is in the other end position, are not located between these two par-ts, so that they are not coupled and no hole is punched.

If such punching arrangements are to be operated at high speeds, the danger arises that the intermediate members cannot be moved fast enough on account of their relatively large mass or that they give rise to bounce or other faults, for instance premature fracture.

It is an object of the invention to overcome these disadvantages by arranging that the coupling between the member controlling the punching movement and each punch is achieved by means of the respective receiving magnet armature in its first end position in such a way that the movement of the armature, or of an extension thereof, which occurs when the magnet is energised or released, takes place in a direction which is substantially perpendicular to the direction of punching and to the lines of holes representing the total of the combination steps and that the armature extension is resiliently movable in the direction of punching.

It is a further object of the invention to provide a punching arrangement which is very simply constructed and which contains only a few components.

It is a further object of the invention to produce an arrangement capable of operating at a high punching speed and occupies only a very small space in spite of the fact that the holes corresponding to the combination steps are arranged very close to each other and may have to be punched simultaneously.

It is a. further object of the invention to provide a punching device in which each receiving magnet armature has an extension which is resiliently movable at least in the direction of punching and the direction of armature attraction. This extension, or the armature itself, may be constructed as a leaf spring and may be twisted between the magnet and its free end through 99.

It is a further object of the invention to provide a punching device in which a frame-like member controlling the punohing movement is directly cam controlled and is formed as a stepped comb for the purpose of guiding the armature extensions, one step being operative when the control member is coupled to the associated punch and the other step being operative when the control member is uncoupled from the associated punch.

Further details and objects of the invention can be seen from the embodiment described hereinafter and illustrated in the accompanying drawings, in which:

FIGURE 1 is a plan view of parts of a punching arrangement according to the invention, in which the tape and the tape-guiding and -transporting means have been omitted,

FIGURE 2 is a perspective view of the components illustrated in FIGURE 1 with only one of the five receiving magnets in position,

FIGURE 3 is a perspective view of the receiving magnet illustrated in FIGURE 2, and

FIGURE 4 is a perspective view of the frame-like control member illustrated in FIGURE 2.

The fast punching arrangement, of which only those parts are shown in the drawing which are essential to an understanding of the invention, includes a continuously rotating cam shaft 1, by which is driven a framelike control member 2. This member is guided at the points 3a and 3b by means of bolts 4a and 4b in such a way that its upper end, which is directed towards the tape 5, carries out an essentially reciprocating movement as the cam shaft 1 rotates. Five punches 6 each of which is allocated to one of the individual combination elements of the telegraph characters and a thin perforation punch 7 are guided in an upper cross member 2a of the frame 2 and in a guide member 8 which lies above the frame. It is assumed that the device being described is intended for use with a five-unit code and accordingly five receiving magnets 9 to 13 are provided. The armatures 1d of these electromagnetic devices carry extensions 15 to 19 which are formed by leaf springs. Each leaf spring is twisted through close to its free end which is located within the frame 2. The arm-atures are kept in their released positions by springs 20.

As can be seen, particularly from FIGURES 2 and 4, the lower internal edge of the frame 2 is formed as a stepped comb. When the frame 2 is in its lowest position, each of the five extensions 15 to 19 is freely movable between the associated punch member and the corresponding comb step. When an armature is in the released position, the free end of the extension attached thereto lies above the channel 20 formed between adjacent projections 2b. The dashed lines in FIGURE 1 illustrate the positions of the extensions under these conditions. As the shaft 1 rotates the frame 2 is lifted, but, so long as the armature remains in the released position, the extension attached thereto is located in the channel 20 and the corresponding punch is not lifted by the frame. If, however, one of the magnets is energised, the free end of the associated armature extension is located between the corresponding punch and the associated projection 2b on the lower internal surface of the frame. When the member 2 is lifted under these conditions, the free end of the armature extension is also lifted and at the same time this extension is flexed in the region between the point at which it is fixed on the armature and the point at which it is twisted. The free end of the armature extension lies between the top of the projection 2b and the corresponding punch, so that the latter is pressed through the paper tape as the frame 2 rises towards its uppermost position. As soon as the member 2 starts its downward movement, the armature extension is free to return to the released position under the influence of the spring 2d when the magnet is de-energised, since there is then no axial force gripping the armature extension between the punch member and the associated projection 212. Therefore, the armature 14 can return to its rest position at the same time and the extension of this armature can again be displaced from the line joining the punch member and the projection 2b of the stepped comb. The projections of the comb may moreover be used also as stops for the armature movement. In particular, in the released position of the armature, it is advisable to utilise as the armature stop that lateral limit of the channel which is opposite to the projection with which the armature extension co-operates when the magnet is energised.

The guide member 8 is provided with bores 22 and 23 for guiding punches 6 and 7, a surface 24 over which the tape slides and cheeks 25 and 26 for aligning the tape 5. A plate 28 is associated with the guide member 8 and this plate is also provided with bores 29 and 30 which correspond in number and shape to the punches 6 and 7.

The advance of the tape 5 is produced through a sprocket cylinder 31 which is driven by a motor (not shown). The drive occurs through the shaft 1, a cam 32, an angle lever 33 and a pawl 34 engaging with a toothed wheel 35. Springs 36 are connected between the pawl 34 and the angle lever 33. It will be appreciated that a friction wheel may be used to advance the tape 5 instead of the sprocket cylinder 31.

In order to accommodate the receiving magnets better, it is advisable, as can be seen in particular from FIG- URE 1, to arrange the magnets and their armatures in such a way that the armatures lie on that side of the magnets which faces the centre of the row of punches. correspondingly, the comb steps in the member 2 on one side of the centre of the row are arranged in the form of mirror images of those on the other side of the centre.

The embodiments illustrated may be modified in various Ways without departing from the scope of the invention. For instance, the receiving magnets may all be arranged on one side of the row of punches. The armatures or armature extensions may be made from round springs or from springs with other cross-sections. The arrangement is useable in a corresponding manner also with those signal storage instruments in which the signals are printed or magnetically recorded instead of being punched.
